Zusammenfassung:PCT No. PCT/EP96/03744 Sec. 371 Date May 18, 1998 Sec. 102(e) Date May 18, 1998 PCT Filed Aug. 23, 1996 PCT Pub. No. WO97/09661 PCT Pub. Date Mar. 13, 1997During the program execution of a user program, the function code assigned to an output signal and the function parameters assigned to this function code are read first. For each function parameter, depending on whether this refers to an input signal or to another instruction, either the input signal is stored temporarily or a branch is made to the other instruction and its function code and function parameters are executed. The generation of the user program is carried out in a similar way. In addition, however, the storage or the as-valid identification of the user program is prevented if the function parameters of all the instructions of at least one output signal have not all been input.
